Classification and use of non-woven fabrics
Date:2021-8-11Visits:333
Non woven fabric is a new generation of environmentally friendly material, which has the characteristics of moisture resistance, breathability, flexibility, lightweight, non combustible, easy decomposition, non-toxic and non irritating, rich color, low price, and recyclability. This material can naturally decompose after being placed outdoors for 90 days, and has a service life of up to 5 years when placed indoors. When burned, it is non-toxic, odorless, and has no residual substances, thus not polluting the environment. It is internationally recognized as an environmentally friendly product that protects the earth's ecology.
Classification of non-woven fabrics
1、 Water jet non-woven fabric
The water jet process is to spray high-pressure fine water onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber webs and giving them a certain strength.
2、 Heat sealed non-woven fabric
Hot bonded non-woven fabric refers to adding fibrous or powdery hot melt adhesive reinforcement materials to the fiber web, and then heating, melting, and cooling the fiber web to reinforce it into a fabric.
3、 Pulp air laid non-woven fabric
Airflow nonwoven fabric, also known as dust-free paper or dry papermaking nonwoven fabric. It uses air flow web technology to loosen wood pulp fiberboard into a single fiber state, and then uses air flow method to aggregate the fibers on the web curtain, and the fiber web is reinforced into fabric.
4、 Wet non-woven fabric
Wet non-woven fabric is made by loosening fiber raw materials placed in an aqueous medium into single fibers, and mixing different fiber raw materials to produce fiber suspension slurry. The suspension slurry is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into fabric.
5、 Spunbond non-woven fabric
Spunbond nonwoven fabric is formed by extruding and stretching polymers into continuous filaments, which are then laid into a web. The web is then self bonded, thermally bonded, chemically bonded, or mechanically reinforced to transform into nonwoven fabric.
6、 Melt blown non-woven fabric
The process of melt blown non-woven fabric: polymer feeding - melt extrusion - fiber formation - fiber cooling - web formation - reinforcement into fabric.
7、 Needle punched non-woven fabric
Needle punched non-woven fabric is a type of dry non-woven fabric that utilizes the puncture effect of needles to reinforce fluffy fiber webs into fabric.
